Lehm Patent No. 67,814, .zaad August 13, 1867.

IMPROVEMENT `Ill GANG-PLOIIGHS.`

TO ALL WHOM IT MAY GONCERN:

Be it known that I, H. I. STAFFORD, of Decatur, in the: county of Macon,and State of llllinois, have invented a new and Yimproved Gang-Plough,and that the following description, taken in connection with theaccompanying drawings, hereinafter referred Ato, forms a full and-exact.specification ofthe same, wherein I have set forth the nature andprinciples of my said improvements, by which my invention may bedistinguished from all others of a similar class, together with suchparts as I claim,`anddcsirc to have secured to me by Letters Patent, l

Thisvinvention relates to a new and improved gang-plough, and consistsin a novel plan or mode of attaching the plough-beams-to the carriage,and also in a novel arrangement of the beams, mode of connecting themtogether, andin a. peculiar application of a lever for moving tlieinvlaterally and vertically, as hereinafter fully shown and described,whereby the driver or operator has'full control over the ploughs, and avery simple and ellcient gang-plough obtained. In the accompanying sheetof drawings- Figure 1 isla. side sectional view of my invention,takenrin the line a: x, fig. 2.

Figure-2, a plan or top view of the same. l l' Similar letters ofreference indicate like parts.

A represents an axle, provided at each end with acrank-arm, B,onvwhich'the wheels C C are i:`ittcd,,andfr1? is a draught-pole,attached to the axle, and braced by a hound, E,'a foot-board, F, beingsecured on the rear' part of the draught-pole and the hound. G is thdriver-s seat, attached `to Van' uprightV securedt'o the rear side ofthe axle A. H H represent two plough-beams, having each a plough, I,attached in the usual orfany proper manner. The beam H is longer thanthe beam II', and the longer beum H has a clevis, J, attached'to itsfront end, in which a double-tree, K,'is fitted, and has a whiietrce,L',Vat each end of it. The front part of this beam H is ttcd loosely ina pendent-swivel guide, M, attached to the draught-pole, said guide'MIworking between pins ain the sides of the beam, as shown in lig. 1. v I

By this arrangement the plough-beams, while beingeounected to thecarriage, admit of'heing-` raisedVv and lowered, and also movedlaterally. The shorter plough-beam H is attached by a pivot, b, to the-beam H, and

the rear part ofthe beam H is fitted in a guide, N,'attached to the rearof H By this arrangement it will be i seen that the plough of beam H maybe raised out of the ground when not required for use, and ma'y besustained in an elevated position by a pin, c. On the top of the heam"Hthere is an oblong staple or loop, O underneath which a grooved roller,d, works, said roller being connected by. a link, e, with the rear endof a lever, P, the fulcrum-pin fof which is in a swivel, Q, in ashort'upright, g, attnchedto the rear of the axle A.

From the above description it will be seen that the driver from hisseat- G, by operating the lever P, may raise and lower the ploughs andmove them to the right or left, as desired, and, in consequence of theteam being attached direct to the plough-beams, the ploughs are made torun perfectly steady, and cross rows of 01d corn and'worlc equally aswell on uneven ground generally as on smooth ground.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. The attaching of the plough-beams to the carriage,through the medium of the pendent-swivel guide M, secured to thedraught-pole D and the pins a n the sides of the beam H, between whichpins the guilde is fitted, substantially as and for the purposespecified.

2. The attaching of the plough-beam H to the beam H, by means of thepivot b and the guide N, substam tially as andfor, the purpose setforth.

3. In combination with the mode of attaching the plough-beams to thecarriage as shown, the application ofthe draught power direct to theplough-beams, substantially as and for the purpose specified.

4. The lever P, having its fulcrum-pin f.fitted in a swivel, Q, on theaxle A, and its rear end connected by l a. link, e, with a groovcdroller, d, which works under an oblong loop or staple, O, on beam H,substantially as and'for the purpose specied.

H. P. STAFFORD.
